DRESS OR SKIRT TRIMMING MECHANISM Filed Jan. 17, 1941 4 Sheets-Sheet 4 ATTOR/YEX present instance, I have shown this disk or wheel as having a serrated or toothed edge portion 22 for providing the garment with a pinked edge, though it will be understood that, as in the alternative embodiment of Fig. 9, the rotatable cutting wheel may have a continuous peripheral cutting edge for'producing a straight line out of the garment material.

On one side of the base plate 20 in parallel relation therewith, a pin or stud 23 is fixedly mounted and supports the pivotally rockable lever 24 in one end of which the pressure'roller 25 is journaled to cooperate with the cutting edge of the disk or Wheel 2| and press the garment material thereon. To the other end of said lever the adjusting screw 26 is connected, whereby the lever 24 may be rocked relative to the base 28 and the pressure of the roller 25 upon the v garment. material regulated as required.

for the purposes of the present explanation.

The above described cutter unit is mounted upon the end of, the rod l8 in adjacent relation to the rotatable'shaft 6 by means of a suitable bracket member 28 fixed at one of its ends to the arm or lug 29 projectingjfrom ones'ide of the base plate 20 and extending below said base plate. The lower end of the bracket member is provided with an opening slidably receiving the. rod l8 and carries the set screw 30, whereby said bracket may be securely fixed in its longitudinally adjusted'positionon said rod. Also said bracket may be rotatably adjusted on the rod [8 to position th'eplate 20 and cutter-wheel 2| in a desired verticalplane with relation to the shaft 6 as may be,found desirable in order to a ply a certain pull or tension to the dress or skirt material. during the cutting operation. To the lower' end of the .shaft 6 and within the housing 1 a cam plate 3| i'sfixed and peripherally coacts with a suitable roller 32 mounted on one end of a lever 33, the other end of which is .fixed to the lower end of the post or trunnion II. A spring indicated at 33 maintains the roller 32 in contact with'the cam 3| and yieldingly resists relative movement of the lever 33. It will thus be understood 'that as the shaft 6 and the dress supporting form are rotated, an oscillating motion is transmitted by the cam, plate 3| and lever 33 to the vertical casing I2 so'that the cutting or trimming unit is bodily moved radially withrespect to the axis ofithe shaft 6. Thus the cutting'u'nit is automatically positioned as required by the width or fullness of the garment so as to obtain an accurate and continuous even out throughout the lower edge of the dress or skirt; j

Preferably, I provide a sliding tapered collar 34 on the rod l8. This collar is urged into frictional binding contact against: the edges of the slot I9 in the wall of the casing l2 by the spring 35 interposed between said collar and collar 36 which is fixed to the rod l8. This provides sufficient resistance to any casual shifting move- 2,383,020 tially in the plane of said base plate. In the ment of the sleeve [6 in the oscillating motion of the casing |2 so that the vertically adjusted position of the cutting or trimming unit will not be altered.

For the further accurate control of the cutting or trimming action, I preferably provide separate rheostats for the motors 9 and 21 which are conventionally indicated at 31 and 38 respectively. The contact arm 39 for the rheostat 31 is adjusted by means of the foot operated treadle '40, while the arm 4| associated with rheostat 3B is adjusted bymeans of the vertically positioned hand operated lever 42. By making the proper adjustments of the respective rheostats, the supply of current to the respective motors 9 and 27 maybe controlled to thereby operate the rotatable dress supporting form 5 and the cutter wheel 2| of the trimming unit at selected speeds. This is a desirable provision to properly trim garments of varying designs particularly dresses which may be provided with numerous pleats, or folds. v

g In the operation of the machine as above described, it will be understood that the trimming or cutting unit is first vertically adjusted relative to the floor surface by theoperation of the adjustingrod 3 to raise or lower the sleeve .|6 and rod |8 so thatvthe point ofcontact of the pressure roller 25 with the cutting edge of the wheel 2| will be located at the required predetermined distance above the floor surface in accordance with the desired length of the skirt. .When

the skirt is draped upon the form'5, its lower edge portion is passed downwardly between the pressure roller 25 and the cutter wheel 2|. When continuous movement of the fabric material between the pressure roller and the cutter wheel so that an even straight out is obtained .around the entire lower edge of the garment at a uniformly spacedfvertical distance above the floor surface.

v In Figs. 4 to 8 of the drawings Ihave illustrated an alternative embodiment of the invention, in which the rotatable perpendicular shaft 6 is driven by the motor 9 through speed reduction gearing 8', as in the construction first described. In. this case, however, the dress w or skirt supporting form 5' is vertically more readily adjustable relative to the shaft 6'. For this purpose, I provide upon the said shaft, int'ermediate of its ends the fixed plate 43 to which the lower ends of aplurality of relatively spaced vertical rods 44 are fixed, said rods constituting guides for the form 5 extending upwardly into suitable bores provided in said form. The upper end of the shaft 6 also rotates freely in a central bore in the form 5'. The lower end of a vertical rack 45 is also fixed to the plate 43,'.thc form 5' having a vertically extending chamber or bore 46 to receive the upper end portionof this rack. I 1 To the lower end face of the form 5' the elongated metal bar 41 is suitably fixed and is provided at one of its ends with an angularly projecting lug terminating in a depending part as indicated at 48. In'spaced relation thereto, said lug is also formed with a second depending part feed member or cylinder 14 isyieldingly held at its base in engagement with the upper face of said cutting disk in the same manner as shown in Fig. 6 of the drawings so that, in accordance with the thickness of the material being fed to the knife blade 9|, said feeding member or cylinder may eccentrically shift relative to the cutting edge of the blade, and thus insure the maintenance of a proper feeding pressure of the material against the cooperating face of the feed roller Tl.

From the foregoing description considered in connection with the accompanying drawings, the construction, manner ofoperation and several advantages of the described embodiments of the invention will be clearly-understood. Practical tests of these machines have demonstrated that in the operation thereof, the dress or skirt will be quickly'and accurately cut or trimmed at its lower edge so that, upon'the body of the wearer, it will be uniformly'spaced for the predetermined distance above the gr under floor surface. The proper operation and control of the trimming mechanism also requires but little manual effort or skill and enables the dress manufacturer to accurately and expeditiously execute such trimming operations'withou't previous marking of the desired-skirt length" on the fabric material. While I have herein shown and described embodiments of my present invention, which I believeto be admirably designed for the purpose in view, it is nevertheless to' be understood that such disclosure, as to many of the mechanical features of the machine, ismo're or less'illustrative, and therefore susceptible "of embodiment in "other alternative structural forms. Accordingly, it is to be understood that in the further development of the present invention I reserve the'privilege of resorting to all such changes in the form, construction and relative arrangement of the several parts as may fairly be comprehendedwithin the spirit and scope of the appended claims.
